一般說明
p53 is a tumor suppressor gene expressed in a wide variety of tissues. It is a tetrameric nuclear DNA-binding phosphoprotein. The gene encoding it is localized on human chromosome 17p13.1.
生化／生理作用
The protein has the capability to induce cell cycle arrest and has a role in DNA repair, senescence and apoptosis. It binds to Simian vacuolating virus 40 (SV40) T-antigen and human papilloma virus E6 protein.
p53 was identified as a tumor suppressor by showing that this protein has the ability to block transformation and to inhibit tumor cell growth. In addition, p53 is a transcription factor capable of regulating the expression of a subset of downstream genes. Mutation of two specific N-terminal residues in p53 (residues Leu22 and Trp23) impairs the ability of p53 to transactivate and has been correlated with its ability to bind TAFII40 and TAFII60 (or TAFII31 and TAFII70) (7, 8) suggesting that one or both of these interactions is important for activation. Mutation of residues 22 and 23 to Ala does not affect binding to TBP, although mutation of these residues to charged amino acids has been reported to disrupt the p53-TBP interaction. Different mutations in p53 gene have been characterized in a variety of human cancers. Loss or mutation of p53 function is highly correlated with tumorigenesis.

Mutations of the p53 gene occur commonly in colorectal carcinomas and the wild-type p53 allele is often concomitantly deleted. These findings suggest that the wild-type gene may act as a suppressor of colorectal carcinoma cell growth. To test this hypothesis

Mutant p53 can contribute to transformation, while wild-type (wt) p53 is not oncogenic and actually inhibits transformation. Furthermore, wt p53 may act as a suppressor gene in human carcinogenesis. We now describe the temperature-sensitive behavior of a particular mutant, p53val135.
